DOOR-STOP.

Specification of Letters Patent.

Patented Sept. 3, 1912.

Application filed January 24, 1912. Serial No. 673,105.

To all whom it may concern:

Be it known that I, ANTOINETTE A. GOFFIN, a citizen of the UnitedStates, re-- siding at Cleveland, in the county of Cuya-' hoga and Stateof Ohio, have invented certain new and useful Improvements in Door-Stops, of which the following is a specification.

The invention relates to safety devices applicable to doors, whereby adoor may be held against opening more than a limited distance.

The invention has for its primary objects; the provision of aninexpensive looking means which is impossible of removal from theoutside of the door; the provision of a locking device which can beremoved only after the closure of the door; the provision of a lockingdevice which can be applied in such a way, as to be inconspicuous andwhich will in no wise injure or deface the door or its surroundingcasing.

Certain embodiments of the invention are illustrated in the accompanyingdrawings, wherein- Figure 1 is a plan view of one form of stop which maybe employed, Fig. 2 is side elevation of the device of Fig. l, with thefloor beneath the stop in section, Fig. 3 is a plan view of the stop asapplied to a door, the dotted lines indicating the position of the doorwhen in closed position, Figs. 4: and 5, and Figs. 6 and 7, are plan andside elevation views respectively of modified forms of construction,Fig. 8 is a plan view of still another form of stop applicable to doorswhich swing in both directions, Fig. 9 is a partial side elevation andpartial section through the stop of Fig. 8, Fig. 10 is an end view ofthe stop shown in Fig. 9, Fig. 11 illustrates in side elevation stillanother form of stop as applied to the bottom of the door, and Fig.12'illustrates still another modified type of construction.

The device is intended to take the place of chains and similar devicesnow in use for permitting a limited opening of the door, but at the sametime preventing such an opening as would permit the entrance of 01jectionable persons, which chain devices and other devices correspondingthereto as heretofore used are more or less objectionable because theydisfigure the door and door framing, and because they cannot be re movedwithout leaving the traces of their attachment upon the woodwork.

It is the purpose of my invention to obviate these difficulties andprovide a device for performing the desired function and a veryinexpensive construction.

Briefly stated, the device in its preferred form, consists of a smallcasting which fits releasably into the floor beneath the lower edge ofthe door and which it is impossible to remove without closing the door.

v The construction will readily appear from an inspection of Figs. 1, 2and 3. The device as here shown consists of a casting 1 with theupwardly projecting rectangular stop2 at one end, and at the other endthe downwardly projecting lug or pin 3, such lug being adapted to engagea socket 4 bored into the floor beneath the door. The device fitsbeneath the door as indicated in Fig. 3, and the upwardly projectingstop 2 engages the rear face of the door and prevents its opening beyondthe point indicated in the full lines. In order that the plate 1 may fitagainst the bottom of the door, a wood strip 5 is secured to the top ofthe plate 1 by means of the screws 6. By chan ing the thickness of thisstrip 5, the device may be made to fit snugly beneath the bottom of thedoor, regardless of the distance of the bottom edge of the door from thefloor. This snug fit between the device and the bottom of the door isdesirable in that it insures a more secure engagement between the pin 3and the socket 4. As will be seen from an inspection of Figs. 1 and 2,the stop 2, and the pin 3 are cast hollow in order to reduce the weightof the device and give a maximum amount of strength in proportion to theweight. The bottom of the plate 1 is also cored out as indicated at 7 inorder to reduce the weight of the device- It will be seen from theforegoing that it is impossible to remove the step without closing thedoor, so that it is absolutely impossible to remove the device andeffect an entrance from the outside of the door. In order to remove thestop the door is swung to the position indicated in dotted lines in Fig.3, after which the stop may be readily lifted from its position ofengagement with the floor. In some cases it may be desirable tostrengthen the socket l by a metal liner, such a construction beingshown in a somewhat different form in Fig. 5.

I11 the construction shown in Figs. 4 and 5 the end of the plate 8 whichfits beneath the door is provided with a hook portion 9 which engages asocket 10 held in position in the floor by means of the screws 11. Thedevice is detached from the floor after the door is closed, by simplylifting the free end of the device vertically. The stop 10 on the plate8 is substantially the same as that shown in Figs, 1 and 2.

In Figs. 6 and 7 still another method of securing the device to thefloor is illustrated. As here shown the socket 12 in the floor isprovided with an irregular elongated opening 13 (Fig. 6), and thedownwardly projecting pin 1 1 on the plate 15 is provided with a flangeportion 16 (Fig. 6). The device is secured in engagement with the socket12 by turning the device at an angle of ninety degrees from the positionindicated in Fig. 6 at which time the flange 16 will pass through theelongated opening 13 in the socket 12. After pressing the pin 14:downward into position it is rotated into the position indicated in Fig.6, in which position it is of course impossible to disengage the deviceby vertical movement.

Figs. 8, 9 and 10 indicate a modified type of construction applicable todoors which swing in both directions. In such construction it isnecessary to provide two stops, the stop 17 serving to engage the frontside of the door, and the stop 18 serving to engage the rear side of thedoor. Instead of a fixed lug or pin for engaging the floor a movable pin19 is provided, such pin being hollow as indicated in the drawing andbeing guided upon the front side of the stop 18 by means of the rivet 20working in the slot 21. In order to disengage thisdevice from the door,the pin 19 must be moved to its upper position, and the device thenslipped endwise to the outside edge of the door.

A construction somewhat similar to that of Figs. 8, 9 and 10 isindicated in Fig. 11. In this construction the bottom plate 22 may besecured permanently to the bottom edge of the door by means of thescrews 23, and the holding bolt 24E is of the type illustrated in thefigure.

In the construction of Fig. 12, the movable pin 25 is used in additionto the fixed pin 26, thus giving a holding means at each end of theplate 27. A wood strip 5 is secured to the top of the plate 25 by meansof the screws 6, the function of such strip being the same as explainedin connection with Figs. 1 and 2.

Having thus described my invention and illustrated its use, what I claimas new and desire to secure by Letters Patent, is the following l. Asafety stop for a door comprising aone piece plate adapted to lieloosely and removably on the floor beneath the door and having a stopprojecting upward from the top of the plate and adapted to engage therear side of the door and having a lug projecting downward from thebot-tom of the plate and adapted to releasably engage a socket in thefloor, the said plate being movable laterally over the surface of thefloor around the said lug as an axis.

2. A safety stop for a door comprising a metal plate adapted to lieremovably on the floor beneath the door and having a stop projectingupward from the top of the plate and adapted to engage the rear side ofthe door, and having a pin circular in cross section projecting downwardfrom the bottom of the plate and adapted to releasably engage a socketin the floor, the said plate being freely removable vertically from thefloor.

3. A safety stop for a door comprising a metal plate adapted to lieremovably on the floor beneath the door and having a stop projectingupward from the top of the plate and adapted to engage the rear side ofthe door, and having a pin circular in cross section projecting downwardfrom the bottom of the plate and adapted to releasably engage a socketin the floor, the said plate being freely-removable from the floor and awood strip removably secured to the top of the plate.

4. A safety stop for a door comprising a plate adapted to lie beneaththe bottom edge of the door; an upwardly projecting stop carried by theplate and adapted to engage the rear face of the door; and a verticallymovable bolt carried by the plate and adapted to engage a socket in thefloor beneath the door.

In testimony whereof I have hereunto signed my name in the presence ofthe two subscribed witnesses.
